UNITED STATES PATENT OFFICE. ORRELL ASHTON, OF LAWRENCE, MASSACHUSETTS, ASSIGNOR TO UIVITED SHOE i MACHINERY COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF NEW JERSEY.

PEGGING-MACHINE.

Patented Apr. 2,

Application filed May 29, 1901 Serial No. 62,341.

To all whom it may concern: v

Be it known that I, ORRELL ASHTON, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented an Improvement in Pegging-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to pegging machines and particularly to machines of the class in which pegs are severed from peg ribbon and then inserted into stock. Machines of this character are commonly used in the manufacture of boots and shoes for securing the outersole to the innersole and to the other parts of the shoe, one or more rows of pegs'being driven around the sole adjacentto its edge.

The machine which is herein illustrated and described as embodying the invention in a preferred form is intended particularly for use in that class of work where it may be desired to insert a plurality of rows of pegs or other fastenings. Since the peg ribbon from which the pegs are formed is usually of wood, it is desirable, if not necessary, to form in the stock openings to receive the pegs before they are inserted and for this purpose, according to one feature of the invention, a plurality of awls are provided. In machines for pegging shoes and particularly in that class in which the shoe is fed by an awl it would be impracticable or impossible to insert two or more awls into the sole and then feed it, since the pegs or 7 other fastenings are inserted along an irregular curved line instead of in a straight line and it is necessary to turn the shoe while it is being fed.

The invention broadly considered, therefore, comprises in one aspect amachine having a plurality of awls which are movable successively into theistock during a single cycle of operations of the machine to form awl holes in a plurality of rows extending along the line offeed of the stock, and actuating devices therefor. In the particular machine herein described one awl as, for example, one which feeds the stock is first inserted and then after the stock has been fed the other awl is inserted. Preferably the awl which first enters the stock only par tially penetrates it but subsequently comsame time that the second awl is fully penetrating the stock.

Another feature of the invention which is most useful in a machine having a plurality of awls but which may be embodied in a machine provided with only one awl is a construction whereby an awl may be rendered operative or inoperative to penetrate the stock at the will of the operator while the machine is continuously in operation. As herein shown, means is provided for feeding the peg ribbon from which the pegs are made either a distance just suliicient for forming one peg or a distance sufficient for forming a plurality of pegs. Preferably this means is arranged to cooperate with the awl controlling mechanism so that when one awl is thrown either out of or into operation the feed of the peg ribbon is correspondingly changed. Hence the machine may be operated to form and insert pegs in either one or two rows and a change may-be made from one to two rows or vice versa at any time.

A further feature of the invention relates to the means for forming the pegs from the ribbon or other material and comprises mechanism for forming a plurality of pegs from a single peg ribbon or piece of material at one stroke or during a single cycle of operations of the machine. Moreover, the machine will preferably include means for forming pegs of a length corresponding automatically to variations in the thickness of the stock being pegged. In such case the peg or pegs about to be driven may be as long as the full width of the ribbon, but if thinner stock is to be pegged, the pegs will be shortened automatically to the proper length, and one feature of the invention comprises means for placing the end of a peg ribbon in the path of movement of a driver and means for forming a shortened peg from the end of the ribbon while it is in such position. In the particular embodiment of the invention herein described, the shoe or other stock to be pegged is supported upon a horn or stock support which constitutes the movable member of means for calipering the stock and which therefore insures the formation of a peg of the proper length.

In addition to the features already specified, the invention comprises certain other combinations and arrangements of parts which are fully set forth in the following detailed description and which are particularly pointed out and defined in the claims at the end of this specification. Moreover, it will be understood that the invention is capable of various other embodiments than the particular one herein specifically illustrated and described and that some of the features may be advantageously employed in other relations. Thus, while the machine illustrated is intended to form and drive wooden pegs, the invention in Whole or in part may be readily embodied in machines for forming or driving other kinds of fastenings, such as nails and slugs, and the fastening material may be supplied to the machine in the form of a wire, a strip or of fastenings already separately formed.

As shown in detail on the drawings, the main frame consists essentially of a column A having, atits lower end, see Fig. 1, suitable'feet to rest on the floor, said column at its upper end having fixed to it, see Fig. l, a head A of suitable shape to sustain'the working parts to be described. The head has bearings to receive the main or actuating shaft A provided with a suitable cam block or disk B, having five cams, two, B and C, made as grooves in the opposite faces of said block, and three,;D, E, F, in the periphery thereof. The cam B imparts motion to the main awl 6, carried by an awl bar 6, fitted to slide in a vertical groove in a feeding carriage G, to be described, represented as movable horizontally on like guide rods G, fixed by screws 23 and 230 in ears A of the head A.

The awl bar I) hasextended. fromit, as

.represented, a stud 12 see dotted lines Fig.

8, which enters a suitable holein a slide block b ,;s ee .Fig. 35, said block entering loosely a groove in the rear side of an arm 6 secured to a rock-shaft 6*", having its bearing in ears A of the head A. Said rock-shaft has fastened to it, see Figs. 1'

and 8, a second arm 6, the latter arm being slidably connected, as by a suitable stud b, with an elbow lever 6 having a sleeve-like hub .mounted loosely on a rock-shaft b",

having its bearings in suitable ears 6 and b, of the head A. The arm Z2 of said elbow lever, see Fig. 10 and dotted lines Fig. 8, has a roller or other stud b which enters thecam groove B, said cam groove imparting vertical motion in the proper time and order to the said awl bar and its awl Z). V The downward movement of this main awl is divided into two steps. The first movement of the awl causes it to penetrate the stock partiallyv only after, which the awl bar and awl are moved laterally with the carriage G, to be described, to feed the stock, and then after the carriage has completed its feeding stroke, and the horn or stock support has risen to caliper and clamp the stock, the awl completes its movement and fully penetrates the stock. These movements of the main awl bar and its awl are produced by the shape of the cam groove B, see Fig. 10, the part thereof between the points 3 .and 4 causing the awl bar and awl to descend to enter and partially penetrate the stock, the part of said cam between the points 4 and 5 holding the awl substantially stationary as to its vertical movement, while the carriage G and the main awl are being moved laterally to feed the stock over the horn, the part of the cam from the point 5 to 6 causing the further or stock penetrating descent of the awl, the part of the cam between the points 6 and-7 causing the awl bar 6 and the awl b to be fully withdrawn from the stock, the awl bar being sustained in raised position by the cam between the points 7 and 3 while the carriage G is being returned to its starting position.

In order that the machine herein shown may be used to drive simultaneously two rows of pegs, I employ an auxiliary awlfe, secured to an auxiliary awl bar 6, herein represented as shorter than the main awl bar Z2, said auxiliary awl bar being fitted into the same groove of the carriage G as the main awl bar (3, see Fig. 38. The auxiliary awl bar slides vertically on or' with relation to the main bar and has extended from it a stud e", which enters a slide 6 like the slide 72 before described, theslide e entering loosely a groove in an arm 6 pinned on the rock shaft 6 said rock-shaft having pinned on it near its other end, see Fig. 1, by a pin 0 a second arm 6 provided with a stud e which enters a slide 6 the latter entering a groove in an arm 0 of a three-arm rocker-lever, the hub of which is mounted loosely on the rock-shaft 19 a second arm 6 see Figs. 10 and 11, re-

ceiving a sliding stud 6 which may be provided with a roll a, maintained thereon as herein shown by a headed screw 6 The stud 2 is acted upon by the cam lump E, see Fig. 10, on the cam block B, the said lump causing the descent of the auxiliary awl bar 0, so that the awl carried by it will penetrate the stock in substantial unison with the main awl 6 while the latter is operating in the second part of its descent to penetrate the stock.' These two awls pass through the stock simultaneously and they are raised from the stock in unison, the rising movement of the auxiliary awl bar and its awl being effected by a third arm 0 of the three-arm lever before referred to. The

arm a has a roller or other stud 6 which,

as the lump E acts to complete the descent of the auxiliary awl, enters the depressed portion of the cam face F, see Fig. 10, and

immediatelythereafter in the further rotation of the shaft A said cam face F acts on said roller 6, and elevates the auxiliary awl bar and its awl in substantial unison with the main awl bar and its awl.

Each awl bar may be bored at its end for the reception of the shank of an awl as shown in Fig. 45, each awl being held clamped therein by a clamp screw 62X having its head countersunk into said bar. It may be desired to form awl holes for but one row of pegs in a portion of the stock. Hence I have provided controlling means whereby the operation of the auxiliary awl may be suspended instantly while the machine is in operation.

I believe that I am the first to employ in a machine for inserting pegs or other fastenings a plurality of awls with means, operable while the machine is running continuously, to put one of said awls into inoperative position, or to suspend its action for any desired number of operations of the machine, so this invention is not limited to the precise means herein represented as embodying this valuable feature of my invention, as it will be obvious that other forms of awl controlling means may be produced without departing from my invention.

The form of controlling device herein represented is the best now known to me, and it consists, as already partially described of a stud 6 see Fig. 11, mounted in the lever 6 said stud being moved longitudinally in or with relation to said lever, it being retracted to withdraw the roll 6 of the stud from the path of the cam E, whenever it is desired that the auxiliary awl bar remain elevated, or in inoperative position.

The withdrawal of the stud 0 may be, and is herein shown as effected by the mechanism now to be described. The end of the stud 6 is recessed to receive one end of a link 6 pivoted on a pin 6 said link having its opposite end 6 shaped to fit over or embrace a stud 6 extended from a link 6, represented as pivoted at 6 in the slotted end of one arm of an elbow lever e fastened to a rock-shaft a, mounted in a suitable bearing A on the head A. The arm e of said lever 6 has jointed to it a rod 6, in turn pivoted at tis lower end to a pin a, of a peg ribbon feed regulator 6 to be described. The pin 6 has connected with it at its opposite end a second rod 6 which is represented as jointed to a lever arm 0 having its fulcrum on a stud screw 6 said lever having a pin 6 over which is fitted one end of a link 6. Said link is jointed to the short arm of a lever 6 herein shown as shaped, see Figs. 1 and 32, to be engaged by the knee or leg of the workman who may turn said lever on its fulcrum e sustained in an ear 6, of the column A. Said lever e is provided with adjusting devices represented as screws 6 and 6 the positions of which may be changed to provide for any desired extent of movement of the stud 6 so that the operator may through said lever instantly put said stud in its operative or in its inoperative position as it is desired to actuate the auxiliary awl bar, or to leave it at rest in its elevated inoperative position. \Vhenever the lever e is in the position shown in Fig. 32, both awl bars are operative, and the acting or left hand end of the lever 626 is in its inoperative position as will be further explained.

The drivers 30 and p are connected, see Figs. 8, 36 86 and 37, with a driver bar 79 by blocks 72 each of which bears upon the shank of a driver resting in a groove at one side of the driver bar, a screw or screws, as 72 securing the drivers firmly to opposite sides of said bar. The drivers are arranged to drive pegs in two rows simultaneously and they are herein shown as positioned to drive the pegs staggered. The driver bar near its upper end, as shown by dotted lines in Fig. 8, has extended backwardly from it a stud p which is embraced by a link f connected at its opposite end with a pin 29 of a crank 79, fast on the front end of the main shaft A, said driver bar thus being actuated positively in both directions. The driver bar enters, as shown, a guideway in the carriage G, before described, in which slide the two awl bars, the edge of the driver bar next the awl bars being notched, see Fig. 38, to leave a projection or ledge which is overlapped by the edge of the auxiliary awl bar e, while the plane edge of said driver bar back of the said notch contacts with the edge of the awl bar 6, the awl bar 6 overlapping the awl bar Z) thus making a very compact arrangement of bars, all of which may be retained in operative position in one and the same groove of the carriage G by a suitable cap 29 screws holding the cap on the carriage, as shown in Fig. 8.

The carriage Gr, carrying the driver bar and awl bars described, has an ear G see Fig. 8, which receives a stud G extended from a slide block G fitted to slide in a slot in an arm G clamped on a rock'shaft G having its bearing in ears A of the head A. The rock shaft has a connected arm G see Fig. at, provided with a roller or other stud 2 which enters the cam groove C, see dotted lines Fig. 10.

Viewed from the front of the machine, the cam-block B rotates in a left-handed direction, as shown by the arrow in Fig. 10, and the cam groove C is so shaped between the points 8 and 9 as to move the carriage, through the mechanism just described, in the direction to feed the stock from the right to the left over the stock support or horn 72. to be described, the awl Z) having par-. tially penetrated the stock and the upward.

pressure of the horn upon the stock at such time being released. Then, while the part of the cam groove between the points 9 and 10 engages the stud 2*, the carriage is maintained stationary. The horn having risen to clamp the stock, the awl bar 6 is made to descend farther and its awl 79 fully penetrates the stock, and if two pegs are to be formed and driven, the awl e is also actuated to penetrate the stock, and while the awl or awls are being -pulled out of the stock, the horn remains in its clamping and calipering position. While the part of the cam from 10 to 12 acts, the awls being then out of the stock, the feeding carriage G is moved backwardly or from the left to the 'nose block orthroat S containing driver passages. The throat is represented de- -tached and enlarged in Figs. to 27, and

is shown in parts in Figs. 16 and 18. Figs. 22, 23 and 24 represent different sections of the throat" and some operative parts much enlarged. The throat S is composed of three blocks or pieces 8, s, and 8 The piece 8 has a driver passage or notch s in which descends the driver 70, the end of the peg ribbon or peg strip 7 entering said passage when tworows of pegs are to be formed and driven, the peg which is to be driven in the row of pegs farther from the edge of the stock standing in said passage. The piece 8 has also a passage t for the auxiliary awl 6, said piece being also shown as notched at its upper side to receive the stationary cutting member or shear block to,

cooperating with the peg shortener to be described, said cutter being held in position in said notch by a screw 8 extended upwardly through a projection s of said piece 8, the head of said screw being accessible at the underside of said projection sf. The projection s of the piece 8 has, see Fig. 16, a longitudinal bore 8 and said piece is bored transversely to receive set screws 3 which are screwed into threaded holes in the part 8 of said throat, thereby clamping said parts together. The part 8 has a pas sage al see Fig 16, through which descends the main awl b, and a driver passage (Z into which the peg former 2., see Figs. 17 and 8, puts a peg to be driven in the row of pegs which isalways to be inserted, said line of pegs making the outside row or, as I have herein designated it, the main row of pegs. The other part 5- of the throat is notched at 214, see Fig. 27, to receive one end of a' peg ribbon carrier to be described, and the offset 8 of said piece 3 is provided with a longitudinal bore 8 corresponding with the bore 8 and the projection s is notched, see

Fig. 18, to form shoulders s to guide and sustain the peg former t. The parts 8 and s are each longitudinally grooved at their upper sides, at at s", and each of said parts is provided with a vertical hole, as 14, 15, which holes receive bolts, one of which, 8 is shown in Fig. 4, said bolts entering threaded holes in the lower edge of the car riage G, said carriage having a projection 8 see Fig. 1, to enter the grooves 8".

Referring briefly to Figs. 28 to 81, Fig. 28 shows the peg ribbon r with its end thrust into the driver groove .9 the end of the peg ribbon represented in section having been shortened by a peg shortening device to be described. This figure shows the peg former retracted and in contact with the outer face of the peg ribbon. Fig. 29 shows the peg former as having been moved to cut the peg ribbon transversely, forming two pegs r" and r 1" being made from the extremity of the ribbon and being left in the driver passage s ,while the peg r is punched out by the former and put by the former into position in the driver passage d. The peg 1' is driven by the driver 17 in the main row of pegs which is always driven, the peg r being driven in the second or, as I style it, the auxiliary row of pegs. i In Fig. 30 it is assumed that but one row of pegs is to be driven and the peg ribbon r is fed only for a distance equal tothe width of one peg, as will be hereinafter described, whereby the end of the peg ribbon does not enter the driver passage 8 so that when the peg 'former t is actuated it willtake but one peg from the extremity of the pegribbon, put-.

ting it in the driver passage (Z as represented by the peg r in Fig. 31.

The peg ribbon r taken from any usual reel, not shown, and of a width equal to the longest peg to be driven, will be led into a groove or way 5?, see Figs. 14 and 19, of a peg ribbon carrier 7?, said carrier in the form in which it is herein illustrated having a hollow shank h which is fitted loosely and made vertically movable in a guideway of the carriage G, so that said peg ribbon carrier may move laterally with said carriage, the shank being covered in said guideway by a plate u" held in place by a screw of the machine is reciprocated very rapidly,

and by making the shank hollow the weight I of the carrier is materially lessened, thereby reducing its momentum. The bottom of the groove of the carrier is closed by a thin steel plate a attached by screws if, said plate sustaining the peg ribbon.

The peg ribbon carrier, see Figs. 12 to 15, has at one side of its receiving opening h lugs or ears h, to thus form between them a slot which may receive the end [L6 of a peg length changing device 7L7, shown as an arm, see Figs. 4 and 12, split at one end and clamped by a clamp screw h on a slide rod h, adapted to slide in a guide it, forming, as shown, part of the head A, the said length changing device having, as rep resented, an intermediate flattened part 71, which is free to be moved vertically in and be guided by a vertical slot 72. see Fig. 10, in a projection h from the head. The lower end of the rod 71*, see Figs. 4 and 10, is provided with a recess to receive the upper end of a horn connection or rod h preferably reduced, as represented, to en ter a recess in said rod h or it may be a hole in the end of the arm if. The lower end of the rod h is united, preferably by a screw thread with the end of an arm h see Fig. 1, attached to the horn spindle h, the latter supporting any usual form of horn or other support for the stock it.

In practice the horn or stock support moves vertically according to variations 1n the thickness of the stock so as to clamp and thus to caliper the stock. As herein shown and described, the peg ribbon carrier is moved vertically substantially in unison with the horn as the latter moves to clamp the stock, and this movement of the carrier provides for the formation of a peg or pegs of a length corresponding to the thickness of the stock then upon the horn, each peg, when a shoe is upon the horn, being of such a length as to have its head driven substantially flush with the outer face of the sole, the inner end of the peg preferably extending slightly beyond the inner face of the insole, so that this projectingend of the peg may thereafter be clenched or broomed, as will be described. The peg ribbon 1" may be fed forward in the peg ribbon carrier by the mechanism now to be described. It may be noted,however, that before the machine is first started the end of the peg ribbon will be pushed through said guideway 7L2 until the end of the peg ribbon meets one side of the peg former t, to be further described, which occupies, when the machine is at rest, a position, see Fig. 31, across the entrance to the driver passage 8 and forming the fourth side for each driver passage, and thereafter, the machine having been started, further movement of the peg ribbon may be controlled and made automatic by the peg ribbon feeding mechanism. One good form of such mechanism is represented as a toothed wheel 1', operatively united by pins 1", see Figs. 7 and 13, with a toothed ratchet wheel r both loose on the eccentric part TX of a stud r to be described, sustained between ears 7', see Fig. 14, of the carrier h the wheels resting in the space between said ears, the periphery of the feeding wheel being extended through an opening 1 in one side wall of said carrier, see Figs. 18 and 14.

The stud T has connected loosely with it, see Figs. 12 and 7 one end of a pawl carrier 1", preferably located between said ears, it being provided with a spring-pressed pawl T of usual construction, one end of said pawl engaging the toothed ratchet wheel r and moving it and the feed wheel r intermittingly in one direction to feed the peg ribbon at the proper times. The upper end of the stud W has clamped firmly on it by a clamp screw 7 an arm 1' which is norngally acted upon by a spring pressed pin r the shank of wh1ch enters a hole r in the carrier 72, said pin acting on said arm and holding said eccentric stud r in such position that the eccentric part TX thereof will keep the feed wheel 1 in contact with the peg ribbon in a yielding manner, whereby the teeth of said wheel may be made to engage the peg ribbon, whatever its thickness. The eccentric portion 1 of said stud is embraced by the feeding wheel and the ratchet wheel so that change of position of the stud moves the said wheels bodily toward or from the path of movement of the peg ribbon.

To actuate the feed wheel r the pawl 1 must be moved, and this may be done in the following manner: The pawl carrier may have connected with it loosely by a suitable screw r a link r provided between its ends, as shown see Fig. 12, with a hole to receive and fit loosely over and slide vertically on a stud r in a lever 1*, the rear end of said link being flattened, as at T to enter and move in a side-notch made in an ear r rising from the peg ribbon carrier operating arm 71. said stud r and said notch insuring at all times the retention of the link r substantially in horizontal position during the changing positions assumed by the carrier under the control of the horn or stock calipering means, so that said link will not be cramped or interfered with to prevent it from moving freely up and down on the stud 1*. To impart to the link r its to and fro movement to actuate the feed wheel, I have mounted the stud r in ears, see Fig. 4, of the lever r pivoted at r on the projection h the said stud being confined in said lever by a clamp screw r. The lever r acted upon at one end by the spring 7 to move the pawl 1' back over the wheel 9", is moved in opposition to said spring by the feed regulator rod h. This rod is actuated by an arm 1 provided with a pin r see Figs. 1, 10, 12, and 20, entering a slot 1 in the head of the said rod 7:.

' scribed.

The rod it has imparted to it itsfeed actuating stroke in the direction of the arrow, see Fig. 12, while the main awl is being withdrawn from the work, and in this movement the head of said rod is always put into the same position, thereby always carrying the pawl to a certain defined forward position, The extent of movement of the feed wheel may, however, be varied by controlling the extent of backward movement of the pawl carrier 1*, and consequently it becomes possible to feed the peg ribbon for a greater or less distance, as may be desired, as when one or a plurality of pegs are to be made at one operation of the machine. Should it be desired to make but one peg at anroperation, the left hand end of the feed-regulator 6 viewing Fig. 1, will be lowered from the position shown in Fig. 10 and by dotted lines in Fig. 20 and put into the position shown by full lines, Fig. 20,,while the arm r is being moved to draw the rod 71. to the right in the direction of the arrow, Fig. 19, thus placing said regulator, in position to be struck by the headh of said rod' h as said rod is being moved to the left by spring 7", the main awl-bar and -awl then descending. After the head h meets regulator 6 the pin 1 of the arm r moves in the slot 7 of the head h during the remainder of its full stroke, said pin sition to arrest the rod h, as stated, inthe backward or inoperative movement of the pawl carrier, then the movement of said pawl is sufiicien't to enable it to pass but one tooth. The foot plate It is slotted at it,

see Fig. 21, to receive the lower end of a nose s s projected downwardly from the parts 8 and s of the multi-part throat S,

- before described. The foot plate is held in place by a set screw u, extended through andholding in'place an edge gage u. The ends of the portionss and s of theparts s, sf, of the throat when said parts are secured t0 the carriage, as stated, form a guideway for the peg former, shown best in Fig. "17, it having a hole 75 The bore .9 8 and the hole t receivethe ball-like end of a universal or ball link 25, see Figs. 8, 12 and 19. The opposite end zf of said universal link or connection is also of ball shape and enters a ball-socket in the block 2?, see Fig. 9, in a groove of a lever 25*, said block having a threaded hole 25 which is entered by a screw 25, see Fig. 12. The lever i pivoted on a stud t fixed to the carriage G, has its upper 'end, jointed looselyto a link t having at its outer end a hole which fits loosely over an eccentric stud i see Fig. 8, said link being held on said eccentric stud by a suitable cap screw t, entering atapped hole in a part of the head A. As the link I, is held at one end fixedly as stated with relation to the head, it follows that as the feeding carriage is reciprocated, the lever t and the peg former will be moved in the same direction as the said carriagebut for greater distance, thus caus ing the peg former to slide in the guideway described for it in the throat,'also attached to the carriage. The eccentric sleeve 25 is provided with holes i which may be engaged to turn theeccentric and thus determine the position of the acting end of the peg former that it may be stopped at the inward stroke at just the proper point so that said former, when a peg or pegs are being driven, may occupy a position to close the open side of and constitute one side of each of the driver passages, see Fig. 29.

The peg ribbon carrier h is limited in its downward movement by a stop 0 applied to the upper end of the slide rod h", which meets the top of the guide h stop- .ping the arm h and the peg ribbon carposition it will occupy in case the pegs being formed are of a length equal to the full width of the peg ribbon. The spring 0 acts to keep the lower end of the slide rod it always in contact with the upper end of the rod h as the horn ascends to caliper and clamp the stock. Fig. 49 shows a modification of this construction in which the rods it and h are kept in contact by a spring h extending from the arm h to the arm it. Such a yielding connection between rods it and k in the mechanism connecting the horn andthe peg ribbon support or carrier is provided in order that the horn may be lowered when it is desired to remove the work from the horn or apply new work to the horn without effecting a corresponding movement of the peg ribbon support. This is an important feature of my invention as it would be undesirable and impracticable for the peg ribbon support tohave as great a movement as the horn when the horn is depressed for the putting on or removing of the work.

The peg shortening device herein shown, embodying my invention in one practical form, consists of a plate 0 presenting a sharp front edge 0 see Figs. 12, 19, 22 and 23, and is carried by a slide bar 0 free to slide in a guideway 0 forming part of the carriage G, said slide bar having jointed to it at one end a link 0 the opposite end of which surrounds an eccentric stud 0 shown detached in Fig. 2', adjustably held clamped in a lever 0 as by a clamp screw 0 said lever having its center of motion at 0 and being provided with a roller or other stud 0 clamped in said lever by a clamp screw, see Figs. 10 and 19, said stud entering and being actuated by the cam groove D. The plate 0 has at its opposite sides transverse grooves 0, 0 forming driver passages, and said plate has holes to receive screws 0 shown by dotted lines Fig. 19, entering threaded holes in the bar or carrier 0, before described, and connecting said plate with said bar. By adjusting the eccentric stud 0 the driver grooves 0 and 0 may be exactly positioned, as required, for the passage therethrough of the drivers 1) and 7), before described.

The peg shortening device is represented as so arranged that it may be moved in a path substantially at right angles to the groove in the peg ribbon carrier, and the edge 0 of the shortener meets the peg ribbon supported at its opposite side by the cutter or block a and cuts the ribbon in the direction of its length to determine the length of the peg to be formed. After the edge 0 outs in this way into the ribbon longitudinally, a further movement of the shortener causes the vertical edge thereof to act in connection with one edge of a shear block p held in place by a screw p to complete the separation of the surplus material not needed in the peg from the ribbon by a vertical cut extending from the longitudinal cut made by the edge 0 to the upper edge of the ribbon, such surplus wood being discharged through the open space above the throat S. Thus, so much of the peg wood or ribbon as is not required for the peg or pegs about to be formed and driven is re moved, so that the peg or pegs are shortened according to the thickness of the stock, since the quantity of material removed as surplus is diminished for thicker stock, and vice versa. During this operation of the peg shortener the peg former t is retracted, as shown in Figs. 19, 22, 28 and 30. If two pegs are to be made, the peg ribbon would have been fed far enough to place its end in the driver passage 8 see Fig. 28, before the peg shortener was operated, so that as the peg former is moved it will act on the ribbon and cut it transversely on two lines back from its front end. In this operation, see Fig. 29, it will make two pegs 1" and 1, the peg r being made from the extremity of the peg ribbon, while the peg r is taken from between that peg and the body of the peg ribbon, the rear side of the peg ribbon acted upon by the peg former being sustained by the face r forming part of the throat piece .9. The peg r is put by the former into the peg driver passage (Z in line with the driver p, while the peg r is left in the peg driver passage 8 in the path of movement of the driver p, and the peg former having arrived in the position shown in Fig. 29, both drivers descend simultaneously and drive the twopegs. If but one peg is to be driven at a time, then the action of the auxiliary awl bar and awl will be suspended, as has been hereinbefore described, the feed regulator 6 being put in posit-ion to meet the head 72, of the rod h and arrest it so that the stroke of the pawl carrier and pawl 1 will be shortened to move the peg ribbon for a less distance, corresponding to the width of one peg, putting the free end of the ribbon in the position in dicated in Fig. 30. In that position the peg shortener will act as before described, and when at the proper time the peg former is actuated to meet the peg ribbon, it will cut therefrom but one peg, moving that peg before it into the driver or peg passage from which it will be driven by the driver 79, the stroke of the other driver which descends as usual, having no effect.

If it is desired for any reason to withdraw the peg ribbon from the machine, the operator will press upon the handle r and turn the eccentric stud 1 carrying the peg ribbon feeding device and ratchet wheel, thus removing the feeding device from contact with the work. The edge of the stock being pegged will be held by the operator against the edge gage 20 made movable toward and from the paths of the awls and drivers by a suitably mounted pinion 14 represented in Figs. 1, 8, and 12. The teeth of said pinion engage teeth formed in a block 211 shown detached in Fig. 43. connected to the edge gage n by a set screw it", extended through a hole 201 and entering a threaded hole in the block 14 the block and edge gage being guided by the foot plate 72, The pinion u and its shaft may be held in adjusted position by means of a spring 14 herein represented as attached to the head of the machine by a screw 202, said spring extending forward and cooperating with teeth of a wheel or ratchet on the shaft.

Viewing Fig. 44 it will be noticed that the edge gage has an extended lip 10 with an upwardly turned projection 24 which engages one side of the foot plate, and the face of the lip is rounded. An edge gage so made prevents any possibility of the work catching between the edge gage and the foot plate. The horn spindle h has fixed to it by a set screw 203 the hub 50 of a .gear 51, and above said gear said spindle
